Secondary Information |

Protein Function | BASP1 strongly interferes with v‐Myc‐induced oncogenicity and displays properties of a tumor suppressor.brain acid-soluble protein 1 gene (BASP1) is specifically downregulated by the v-myc oncogene and that ectopic BASP1 expression inhibits v-myc-induced cell transformation. |
---|
Biochemical Properties | The 11-amino acid effector domain of the BASP1 protein interacts with the calcium sensor calmodulin (CaM) and is mainly responsible for this inhibitory function. The BASP1 effector domain acts like a CaM inhibitor and interferes with MYC‐dependent oncogenesis |

Additional Comments | BASP1 belongs to the GAP43/myristoylated alanine‐rich C‐kinase substrate (MARCKS)/CAP‐23 family of myristoylated neuronal growth‐associated proteins and shares distinct biochemical properties with the other members MARCKS and growth‐associated protein 43 which also bind CaM by their basic EDs. Phosphorylation by PKC leads to disruption of the interactions of BASP1 with membrane lipids or CaM. BASP1 can then be translocated into the nucleus where it attenuates the transcriptional activity of the Wilms’ tumor suppressor protein WT1, thereby acting as a transcriptional cosuppressor, which also drives cell differentiation processes |
